Assumption: Audio signal is a +4 dBU line level signal DC-biased to not go into negative region. Audio source has a low output impedance. Assumed signal voltage, as per above: V signal = 1.737 Volts peak + 1.8 Volts DC bias. The STP16NF06L N-channel MOSFET can be used as a voltage controlled switch, thus:
